EDWARD R. BUCHANAN, OF PITTSBURGH, PENNSYLVANIA.

VJINDSHIELD.

Application filed August 23 7 0 all whom it may concern:

Be it known that If, Enwann R. BUCHANAN, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful lnnorovements in Vindshields, of which the following is a specification. 1

This invention relates to Windshields for vehicles, and it has for its object the production of suitable means for supporting the windshield, so that, if any of the occupants are inadvertently thrown forwardly against the shield it will be pushed out of the frame so as not to injure the occupants or break the shield.

' Of the accompanying drawings, Fig. 1 is an elevation of a pair of Windshields, the supports of which embody the features of my invention; and Figs. 2 and 3 are sectional views along the respective lines 2 and 3 of Fig. 1.

My invention comprises means for supporting the windshield so that it can be pushed out of its frame, but it is to be understood that the entire shield or one end only may be thus forced out. For instance, the shield may be hinged at one end and arranged so that it will be forced outat the other end in case of an accident. I prefer to have both of the shields hinged on the side of the vehicle where the driver sits, as is indicated. in Fig. 1 which is an elevation of the shields and frame when looking at them from in front of the vehicle. I then arrange so that the other ends of the shields will be yieldingly detachable so that they can be forced out in case of an accident sh as to prevent injury to the occupant at that end. As the shields are supported by the hinges at one end they are much less likely to be broken, and the driver is usually prevented from being thrown against the shields by the steering wheel. But even if he should be thrown against the shields they will give at the detachable end before breaking.

Any suitable means may be provided for detachably holding the ends of the shields in place so that they may be pushed forwardly. I prefer for the purpose bearing blocks 5 which are removably mounted in the shield frame 6 by being positioned in recesses 7 formed in any suitable manner in the frame. Springs 8, pivoted to the frame, are so formed as to securely hold the hearings in place for all ordinary purposes but will give 1922. Serial No. 583,741.

sufficiently to allow either bearing to be forced outwardly in case of an accident before the glass of the shield is broken. Any suitable li iotlll-S may be provided rotatably supporting the shields and for holding each shield in any adjusted position as it is turned in the bearing 5. I prefer to use a pin 9, which is fixed to the sash 10 of the glass shield 11 and on which the glass turns in a usual manner. This pin, however, after passing through the bearing 5 continues through a slot 12 in the frame of the shield, and also through a collar 13 which is positioned between the bearing 5 and a knob nut 1 1 threaded onto the outer end of the pin. By screwing the knob Lt. tightly against the collar, rotation of the sash on the pin will be prevented unless cosnaiderable force is.

used. The conical end of the collar positioned in the conical bore of the bearing, materially increases the friction preventing rotation of the pin. This not only will prevent the sash from turning except when desired, but will prevent any rattling of the various parts.

When anyforce from the inside of the vehicle is sutlicient the spring 8 will give and the bearing 5, the pin 9 and the nut 14, as well as the adjacent end of the sash and the glass, will be forced outwardly. In replacing the bearing the spring is turned to one side, the bearing is placed in the recess and the spring is then turned back into place and is held in position by means of a recess 15 in the face of the bearing.

The other end of the sash 10 is pivoted on a pin 16 which is fixed to one arm of a hinge 17. The other arm 18 of the hinge is fixed, in any suitable manner, to the frame 6 of the shield; it being understood, however, that the exact method of pivoting or hing ing the sash to the frame is not material to my invention, providing only the arrangement is such that the detachable end of the sash is free, so far as the hinging is concerned, to be forced outwardly.

I claim as my invention:

1. A windshield comprising a sheet of stiff material, and a frame, one end of said shield being pivoted vertically to said frame for horizontal rotation and the other end being detach-ably fixed thereto, and yielding means fixed to said frame adjacent the other end and holding said other end in operative position.

A frame, a windshield, and means detachably connecting said shield to said frame, said means comprising a bearing block detachably mounted in said frame, one end of said shield being rotatively connected to said bl ck, and a spring With one end fixed to said frame and the other end passing over said block.

3. A. frame, a Windshield, and means detachably connecting said shield to said frame, said meanscomprising a bearing block detachably mounted in said frame, one end of said shield being rotatively connected to said block, and a spring with one end fixed to said frame and the other end passing over said block, the other end of said shield being pivotally connected to said frame.

4%. A frame, a Windshield, and means operatively connecting said frame and shield, said means comprising a bearing block having a bore therethrough, a pin horizontally fixed to one end of said shield and positioned in and passing through said bore, and with the outer end projecting a material distance beyond said block, a nut threaded onto said end, said frame having an open recess on one side thereof, said block being non-rotatively but detachably mounted in said recess, and yielding means holding said block in said recess.

5. A frame, a windshield, and means operatively connecting said frame and shield, said means comprising a bearing block having a bore therethrough, a pin horizontally fixed to one end of said shield and positioned in and passing through said ore, and with the outer end projecting a material distance beyond said block, a nut threaded onto said end, said frame having an open recess on one side thereof, said block being non-rotatively but detachably mounted in said recess, yielding means holding said block in said recess, and a collar on said pin between said nut and block, said frame having an open slot adjacent said recess, and said collar being positioned in said slot. y

6. A frame, a Windshield, and means operatively connecting said frame rand shield, said means comprising a bearing block having a bore therethrough, a spin horizontally fixed to one end of said shield and positioned in and passing through said bore, and with the outer end projecting a material distance beyond said block, a nut F threaded onto said end, said frame having an open recess on one side thereof, said block being non-rotatively but detachably mounted in said recess, yielding means holding said block in said recess, a collar on said pin between said nut and block, said frame having an open slot adjacent said recess, said collar being positioned in said slot, the outer end of said bore being conical and the adjacent end of said collar being positioned in and conforming to the shape of the outer end of said bore. a

7. A frame, a Windshield, and means detachably connecting said shield to said frame, said means comprising a bearing block detachably mounted in said frame, one end of said shield being rotatably connected to said block and yielding means holding said block in its normal position in said frame.

8. A frame, an elongated horizontally mounted Wind shield, and means detachably connecting one end of said shield to said frame, said means comprising a block movably mounted in said frame, the end of said shield being rotatably mounted to said block, and yielding means fixed to said frame adjacent said block for holding said block in its normal position in said frame.

In testimony whereof, I hereunto set my hand.

EDWARD R. BUCHANAN.
